Abstract: The present invention relates to an electrochemical fuel cell device having stacked cells and a membrane-electrode assembly (20). The membrane-electrode assembly (20) comprises, amongst others, a first gas diffusion layer (21) arranged on one side of a membrane (23) and a second gas diffusion layer (22) arranged on the opposite side of the membrane (23) for distributing fluids across each side of the membrane (23).

Abstract: Simple membrane electrode and frame assemblies for a solid polymer electrolyte fuel cell stack and improved methods for making them are disclosed which involve the use of a single adhesive layer. Using an appropriate design, the single adhesive layer can provide multiple bonds, including a bond between one of the gas diffusion layers and a catalyst coated membrane assembly, between the catalyst coated portion of the catalyst coated membrane assembly and the frame, and between either the other of the gas diffusion layers and the frame, or between an uncoated portion of the catalyst coated membrane assembly and the frame.
